3 tools

  • analyze_manifest

    Static privilege analysis of a Chrome MV3 manifest.json. Returns a 0-100 risk score, the permissions and host patterns that drive it, dangerous permission combinations, and MV3 policy problems (remote code, unsafe-eval, <all_urls> web_accessible_resources). Content-script matches

  • explain_permission

    Returns the privilege weight (0-10) for a single Chrome extension permission or host pattern, what it actually grants, whether it triggers an install-time warning, and the narrower alternative if one exists.

  • compare_permission_sets

    Compares the permissions and host patterns of two versions of an extension. Reports the score delta, what was added or removed, and whether the change widens the install-time warning set, which makes Chrome disable the extension for existing users until they re-accept.

Security scan

  • No findings. We scan names, descriptions and tool definitions for hidden instructions and other prompt-injection patterns.
